Flexible bag for containing and dispensing liquid

Abstract

A flexible bag assembly for containment and dispersal of liquids includes a bag having flexible front and back panels, and a peripheral side panel structure interconnecting the front and back panels at sealed seams, the panels defining a chamber for retaining the liquid, a water-proof zipper disposed in the front panel, a detachable cover member fixable to an outside surface of the front panel and adapted to cover the zipper, and a closeable and openable tube extending from within the chamber, through one of the panels and outwardly therefrom, the tube being adapted to facilitate the selective dispersal of the liquid from the bag.

1. A water-proof air-tight, flexible bag assembly for containing and dispensing liquid, and for surviving an air-drop of up to 100 feet, the assembly comprising:
 a bag having a front panel, a back panel, and a peripheral side panel, each said panel having an interior surface and an outer surface, and each said panel being flexible and consisting of silicone nylon fabric, wherein the periphery of the front panel is joined to the side panel at a first scam, said first seam being sealed with a silicone adhesive, and the periphery of the back panel is joined to the side panel at a second seam, said second seam being sealed with a silicone adhesive, said front, back, and side panels being interconnected at said seams, and said seams being sealed with a silicone adhesive for defining a chamber formed by a silicone nylon fabric panel joined to another silicone nylon fabric panel at a seam, said seam being sealed with a silicone adhesive for retaining the liquid, said chamber being further defined by the interior surface of each said panel; 
 a zipper, being air-tight and water-proof, said zipper being mounted in a zipper panel, said zipper panel being fixed hermetically to the outer surface of the front panel and being sealed to the front panel with an adhesive, said adhesive being silicone on silicone adhesive; 
 wherein said silicone nylon fabric being flexible for rendering the bag assembly collapsible when said bag assembly is empty; and wherein said fabric consisting of unidirectional woven silicone nylon, ranging from 500 to 1000 Denier, said interior surface of each said panel being coated with an anti-microbial material; 
 a cover being detachably fixable to the outer surface of the front panel for covering the zipper and providing air-drop impact protection to the zipper; and 
 a tube extending outwardly from said chamber and though a said panel, said tube being closeable and openable, and said tube being for dispersing liquid from the bag; 
 wherein said chamber for containing a liquid and an air pocket, said liquid and air pocket forming a liquid surface within the bag; and wherein said zipper being disposed such that the zipper opens for opening an air-containing portion of the bag for allowing air to enter the bag as liquid is drawn from the bag through said tube, and said zipper is of sufficient length, when open, for pulling the interior surface of said chamber through the opened zipper for reversing the bag such that the interior surface becomes outside the bag for cleaning the interior surface.
